CROSS REFERENCE TO RELATED APPLICATION

This application is a continuation of U.S. patent application Ser. No.09/995,142, filed Nov. 27, 2001 now U.S. Pat. No. 6,792,081.

BACKGROUND OF INVENTION

The present invention is directed generally to notification systems,and, more particularly, to an emergency notification system.

In today's society, there are increasing numbers of people who work atlocations other than their homes. In many instances, there are youngchildren who spend considerable amounts of time at home without adultsupervision while their parents are working. Such situations can be verystressful to a working parent because of the uncertainty of knowingexactly what the unsupervised children may be doing. There are also agrowing number of exactly people who have elderly parents living alone.Understandably, there are many people who, for various reasons, desireto be notified as soon as possible if an emergency call is placed from alocation that concerns them.

One service that has attempted to address this desire is the family 911notification service offered by Lucent Technologies Inc., Murray Hill,N.J. Each subscriber to the service may select up to five telephonenumbers, each associated with a particular person, that they wish to becalled if a 911 call is placed from a landline telephone associated withthe subscriber. The selected telephone numbers may be given a priorityfrom first to fifth and may be associated with landline telephonesand/or wireless telephones. The service operates in the manner describedhereinbelow.

After a 911 call has been placed from a landline telephone associatedwith a subscriber, the service calls the selected telephone numbers in asequential order according to the specified priority. If the family 911notification service reaches a live person at one of the selectedtelephone numbers, the service plays an announcement. The announcementinforms the person that the incoming call is from the family 911notification service and that a 911 call was placed. The announcementalso informs the person as to the time that the 911 call was placed andthe telephone number that the 911 call was placed from. The servicestops calling the selected telephone numbers once the information hasbeen provided to a live person. If the service has not reached a liveperson after all of the selected telephone numbers have been called, theservice waits for five minutes before beginning to call the selectedtelephone numbers again. This process repeats itself for the first hourfollowing the placement of the 911 call. During the first hour, if theservice reaches an answering machine or a voice mail system at one ofthe selected telephone numbers, the service does not play anannouncement.

If the service has not reached a live person within the first hour, theservice continues to call the selected telephone numbers according tothe specified priority. However, if the service reaches an answeringmachine or a voice mail system after the first hour, the service plays aslightly different announcement. This announcement informs the answeringmachine or voice mail system that the incoming call is from the family911 notification service and that the service has been trying to reachthe person associated with the selected telephone number to notify themthat a 911 call has been placed. This announcement also informs theanswering machine or the voice mail system as to the time that the 911call was placed and the telephone number from which the 911 call wasplaced. The service stops dialing the selected telephone numbers once anannouncement has been played to an answering machine or a voice mailsystem. If the service has not reached a live person, an answeringmachine, or a voice mail system within the first twenty-four hoursfollowing the placement of the 911 call, the service stops dialing theselected telephone numbers.

There are several shortcomings associated with Lucent's family 911notification service. For example, the means used to provision theselected telephone numbers add complexity and cost to the service, thehardware used to implement the service is relatively expensive toacquire and maintain, and the service only offers oral notification thata 911 call has been placed. Thus, there exists a need for an emergencynotification system that overcomes the limitations, shortcomings, anddisadvantages of the emergency notification system describedhereinabove.

DETAILED DESCRIPTION OF THE INVENTION

It is to be understood that the figures and descriptions of the presentinvention have been simplified to illustrate elements that are relevantfor a clear understanding of the present invention, while eliminating,for purposes of clarity, other elements of a conventionaltelecommunications network. For example, certain operating systemdetails and modules of certain of the intelligent platforms of thenetwork are not described herein. Those of ordinary skill in the artwill recognize, however, that these and other elements may be desirablein a typical telecommunications network. However, because such elementsare well known in the art, and because they do not facilitate a betterunderstanding of the present invention, a discussion of such elements isnot provided herein.

The term “calling party” is used herein generally to refer to the personor unit that initiates a telecommunication. The calling party may alsobe referred to herein as “caller.” The term “called party” is usedherein generally to refer to the person or unit that answers or respondsto the call or communication. In some cases the calling party or thecalled party may not be a person, but may be a device such as ananswering machine, a voice mail system, etc. The term “communication” isused herein to include all messages or calls that may be exchangedbetween a calling party and a called party, including voice, data andvideo messages. The term “communication” is used synonymously hereinwith the term “call” unless a distinction is noted. The term“subscriber” is used herein to generally refer to a subscriber of thedescribed emergency notification service.

The present invention is directed to an emergency notification system.According to one embodiment, the emergency notification system utilizesthe intelligent functionality of an Advanced Intelligent Network (AIN).The AIN is a network used to provide enhanced voice and data servicesand dynamic routing capabilities to a conventional telephone network.With AIN, the actual voice call is still transmitted over acircuit-switched network but the signaling and control takes place on aseparate packet-switched network. Before describing details of thesystem of the present invention, a high-level description of an AIN isprovided.

FIG. 1 is a block diagram of an Advanced Intelligent Network (AIN) 10.The AIN 10 may be employed by a Local Exchange Carrier (LEC), and may beutilized by the LEC to allow the LEC to provide call processing featuresand services that are not embedded within conventional switchingcircuits of a conventional telephone system such as, for example, thePublic Switched Telephone Network (PSTN) 12. As illustrated in FIG. 1,the AIN 10 includes a Service Switching Point (SSP) 14, a Signal ControlPoint (SCP) 16, a database 18, a Signal Transfer Point (STP) 20, and aService Node (SN) 22.

In a conventional telephone system, central office (CO) switches areused to interconnect customer premises equipment (i.e., terminalequipment such as telephones, modems, or answering machines that areconnected to the telephone network and reside on the customer'spremises). For the AIN 10 illustrated in FIG. 1, the SSP 14 is a switchused to interconnect customer premises equipment via the PSTN 12. Thedifference between the SSP 14 and the CO switch of a conventionaltelephone system is that the SSP 14 provides intelligent networkfunctionality.

The SSP 14 has one or more subscriber lines 24 connected thereto. Thesubscriber lines 24 may be, for example, local loops comprisingconventional twisted pair loop circuits connected between the SSP 14 andthe customer premises, or the subscriber lines 24 may be trunk circuits,such as T-1 trunk circuits. The number of subscriber lines 24 connectedto an SSP 14 may be on the order of ten thousand to one hundred thousandlines. The subscriber line 24 is connected to a terminating piece ofcustomer premises equipment, represented in FIG. 1 by a landlinetelephone 26. Alternatively, the terminating equipment may be any othertype of communications unit such as, for example, a telecopier, apersonal computer, a modem, an answering machine, or a private branchexchange (PBX) switching system.

The SCP 16 is a server, associated with a database 18, and providesinstructions to the SSP 14 and the SN 22 as requested and required. TheSCP 16 may be an intelligent database server such as, for example, anIntelligent Network Service Control Point available from LucentTechnologies Inc., Murray Hill, N.J. The database 18 is for storingcustomer information used in providing enhanced calling services, suchas the service provided by the emergency notification system of thepresent invention, and may reside at the SCP 16. The intelligentfunctionality of the SCP 16 may be realized by application programs,such as programmable Service Program Applications (SPA), which areexecuted by the SCP 16. Although the AIN 10 illustrated in FIG. 1 onlyshows one database 18 associated with the SCP 16, it is understood thatmore than one database 18 may be associated with the SCP 16.

The STP 20 is a packet switch that routes signaling and control messagesbetween the SSP 14 and the SCP 16. As illustrated in FIG. 1, the STP 20is in communication with the SSP 14 via communication link 28 and withthe SCP 16 via communication link 30. Communication links 28, 30 mayemploy, for example, the Signaling System 7 (SS7) signaling protocol.

The SN 22 may provide an enhanced feature or service that requires anaudio connection between the SN 22 and an answering machine connected toa subscriber line 24, or between the SN 22 and a landline telephone 26from which an emergency communication has been placed. The SN 22 may beany type of AIN-compliant service node, and may be, for example, aCompact Services Node (CSN) available from Lucent Technologies Inc.,Murray Hill, N.J. Similar to the SCP 16, the intelligent functionalityof the SN 22 may be realized by programmable applications executable bythe SN 22.

The SN 22 is in communication with the SSP 14 via communication link 34,with the PSTN 12 via communication link 36, and with the SCP 16 viacommunication link 38. Communication links 34 and 36 may be, forexample, an Integrated Service Digital Network (ISDN) Primary RateInterface (PRI), an ISDN Basic Rate Interface (BRI), or a T-1 trunkcircuit. Communication link 38 may be, for example, a portion of acommunication network such as, for example, a Local Area Network (LAN),a Metropolitan Area Network (MAN), or a Wide Area Network (WAN).

The basic operation of the AIN 10 illustrated in FIG. 1 is describedhereinbelow. When a call originating from the landline telephone 26 isreceived at the SSP 14 via the PSTN 12, the SSP 14 generates a query todetermine how the call should be processed. The query generated by theSSP 14 is transmitted via out-of-band signaling through the STP 20 tothe SCP 16.

The SCP 16 interprets the query based on information provided by the SSP14 and information stored in the database 18 to determine whether somecustomized call feature or enhanced service should be implemented forthe particular call, or whether conventional dial-up telephone serviceshould be provided. The information provided by the SSP 14 may include,for example, the originating telephone number, the name of the callingparty, and the telephone number dialed by the calling party. Theinformation stored in the database 18 may include, for example, routinginstructions associated with the dialed telephone number. Once the SCP16 determines how the call is to be processed, it returns a messagethrough the STP 20 to the SSP 14 instructing the SSP 14 how the callshould be processed. The instructions may be to take some special actionas a result of a customized calling service or enhanced feature. Forexample, for an enhanced calling feature requiring the capabilities ofthe SN 22, the return message from the SCP 16 may include instructionsfor the SSP 14 to route the call to the SN 22. In addition, the returnmessage from the SCP 16 may simply be an indication that there is noentry in the database 18 that indicates anything other than conventionaltelephone service should be provided for the call. The query and returnmessages may be formatted, for example, according to conventional SS7TCAP (Transaction Capabilities Application Part) formats.

Although the AIN 10 illustrated in FIG. 1 includes only one SSP 14, oneSCP 16, one database 18, one STP 20, and one SN 22, it is understoodthat the AIN 10 may further include an additional number of thesecomponents as well as other network components that are not included inFIG. 1 for purposes of clarity. For example, the AIN 10 may additionallyinclude redundant SCP's and STP's to take over if the SCP 16 or the STP20 should fail. Further, the AIN 10 may include regional STP's andregional SCP's in communication with, for example, the local STP 20, forrouting and servicing calls between different LECs.

FIG. 2 illustrates a system 40 employed by an emergency notificationservice, such as the Lucent family 911 notification service. The system40 includes the AIN 10 as described hereinabove with regard to FIG. 1,and also includes a web server 42 and a Service Management System (SMS)44. The web server 42 is connected to the Internet 46, and is incommunication with the SMS 44 via communication link 48. Communicationlink 48 may be, for example, a portion of the communication network thatincludes communication link 38.

The SMS 44 is an operations support system used to facilitate theprovisioning and administration of service data required by the SCP 16.The SMS 44 includes a network server and a database, and may be used tocentralize and manage the service logic and customer data residing atthe SCP 16. The SMS 44 includes programmable applications executable bythe SMS 44 that provide access to the service management functions ofthe SMS 44 such as, for example, subscriber provisioning, and provide adirect interface to the SMS database. The SMS 44 is in communicationwith the SCP 16 via communication link 50. Communication link 50 may be,for example, a portion of the communication network that includescommunication link 38.

When a customer subscribes to the emergency notification service, theservice is provisioned at the SCP 16. Information provisioned at the SCP16 may include the name of the customer, the customer's landlinetelephone number, and the telephone numbers that the customer wishes tobe called when a 911 call originates from the customer's landlinetelephone number. The customer may designate up to five telephonenumbers that the customer wishes to be called when a 911 call originatesfrom the customer's landline telephone number. A system administratormay provision the service by entering the information via the SMS 44,which in turn passes the information to the SCP 16, which then populatesthe database 18 with the information. Alternatively, the subscriber mayprovision the service remotely via the Internet 46 by providing theinformation to the web server 42, which in turn passes the informationto the SMS 44 for provisioning at the SCP 16 as described hereinbefore.

When a 911 call is placed from the customer's landline telephone 26, thecall is passed to the SSP 14 via the subscriber line 24 connecting thelandline telephone 26 to the SSP 14. The call activates a triggerdefined at the SSP 14, resulting in a query message being sent to theSCP 16 via the STP 20. A trigger is an event associated with aparticular subscriber line 24 that causes the SSP 14 to query the SCP 16for instructions as to how to process the call. A trigger may be anoriginating trigger for a call originating from the customer premises ora terminating trigger for a call terminating at the customer premises.The query message includes a caller ID message giving the customer'stelephone number, and the date and time that the 911 call was made. Thecaller ID message may also include the name of the customer. The SCP 16receives the query message and returns a response message to the SSP 14via the STP 20. The response message instructs the SSP 14 to process the911 call as a switch-based feature. The SSP 14 then routes the 911 callto a Public Safety Answering Point (PSAP), where a PSAP operatorverifies or obtains the caller's location, determines the nature of theemergency, and decides the appropriate emergency response. For example,the PSAP operator may dispatch help directly, or may transfer the callerto a secondary PSAP from which help will be dispatched. Secondary PSAP'sare typically located at fire dispatch areas, municipal police forceheadquarters, or ambulance dispatch centers.

In addition to returning the response message to the SSP 14, the SCP 16also uses the information provided by the query message to search thedatabase 18 to determine if the customer is a subscriber to the family911 notification service. If the customer is subscribed to the service,the calling of the designated telephone numbers is initiated. If thecalling is initiated, the SCP 16 makes a TCP/IP connection request tothe SN 22. Once the TCP/IP connection is established between the SCP 16and the SN 22, the SCP 16 transmits information to the SN 22. Theinformation includes the telephone number from which the 911 call wasmade, the time and date of the 911 call, and the designated telephonenumbers to be notified for the subscriber. Once the information has beenreceived at the SN 22, the TCP/IP connection between the SCP 16 and theSN 22 is released.

The SN 22 will then begin placing outgoing calls to the designatedtelephone numbers in a sequential manner. As described hereinbefore, ifthe SN 22 reaches a live person at one of the designated telephonenumbers, the SN 22 announces that the incoming call is from the family911 notification service, that a 911 call was placed, the telephonenumber from which the 911 call was placed, and the time that the 911call was placed. The SN 22 stops dialing the designated telephonenumbers once the announcement has been played to a live person. If theSN 22 has not reached a live person after all of the designated numbershave been called, the SN 22 waits for five minutes before beginning tocall the designated telephone numbers again. This process repeats itselffor the first hour following the placement of the 911 call. During thefirst hour, if the SN 22 reaches an answering machine or a voice mailsystem at one of the designated telephone numbers, the SN 22 does nottransmit the announcement.

If the SN 22 has not reached a live person within the first hour, the SN22 continues to call the designated telephone numbers according to thespecified priority. However, if the SN 22 reaches an answering machineor a voice mail system after the first hour, the SN 22 transmits anannouncement that the incoming call is from the family 911 notificationservice, that the service has been trying to reach the person associatedwith the designated telephone number to notify them that a 911 call hasbeen placed, the telephone number from which the 911 call was placed,and the time that the call was placed. The SN 22 stops dialing thedesignated telephone numbers once this announcement has been played toan answering machine or a voice mail system. If the service has notreached a live person, an answering machine, or a voice mail systemwithin the first twenty-four hours following the placement of the 911call, the SN 22 stops dialing the designated telephone numbers.

One skilled in the art will recognize several shortcomings associatedwith the above-described system 40. For example, all of the subscriberinformation needed to operate the notification service must beprovisioned via the SMS 44, adding cost and complexity to the system 40.Furthermore, storing this information at the SCP 16 requires increasedstorage capacity at the SCP 16, resulting in increased acquisition andmaintenance costs. In addition, the SN 22 employed in the system 40 is avery expensive network element, often having an initial purchase priceof approximately one-half million dollars.

FIG. 3 illustrates an emergency notification system according to oneembodiment of the present invention. The system 60 includes a switch 62,a database server 64, a message server 66, and a web server 68. Thesystem 60 also includes an STP 20 as described hereinbefore. The system60 is used to provide an emergency notification service that transmits amessage that an emergency communication was placed from terminalequipment associated with a subscriber to the service.

The switch 62 may be in communication with terminal equipment such as,for example, a landline telephone 26 associated with the subscriber viaa subscriber line such as, for example, subscriber line 24. According toone embodiment, the switch 62 may be a service switching point such as,for example, the SSP 14 as described hereinabove. The switch 62 mayinclude an originating trigger such as, for example, an N11 trigger, andthe N11 trigger may be, for example, a 911 trigger. The switch 62 mayalso be in communication with the STP 20 via communication link 28 andwith the message server 66 via communication link 34.

The database server 64 is in communication with the switch 62 via theSTP 20 and communication links 28 and 30, and may be a service controlpoint similar to the SCP 16 described hereinbefore. The database server64 may store call-processing instructions, and may supply instructionsto the switch 62 concerning how to process an incoming call. Forexample, according to one embodiment, the database server 64 may supplythe switch with instructions for processing an emergency communicationreceived at the switch 62. Although the database server 64 may besimilar to the SCP 16, the database server 64 is markedly different fromthe SCP 16 in that the database server 62 does not maintain theprovisioned subscriber information (i.e., subscriber name, subscribertelephone number, telephone numbers to be called, etc.) associated withthe emergency notification service. Therefore, the database server 64may be provided with less storage capacity and require less databasemaintenance than the SCP 16. Accordingly, the database server 64 mayhave a lower initial cost than the SCP 16 and have lower maintenancecosts associated therewith.

The database server 64 may also supply information associated with anincoming call to the message server 66. For example, the database server64 may supply the message server 66 with information associated with anemergency communication. Such information may have been provided to thedatabase server 64 by the switch 62 and may include, for example, thename of the person associated with a subscriber line 24 from which theemergency communication originated, the telephone number from which theemergency communication originated, and the date and time that theemergency communication was received at the switch 62.

The message server 66 is in communication with the database server 64via communication link 70, and may transmit a message after an emergencycommunication is received at the switch 62. The message server 66 may beany type of low-cost computer suitable for transmitting an oral messageand/or a textual message. Whereas the SN 22 employed in system 40 has aninitial cost of approximately one-half million dollars, the messageserver 66 only has an initial cost of approximately ten-thousanddollars. According to one embodiment, the message server 66 may be atelephony server that may transmit an oral message. According to anotherembodiment, the message server 66 may be an electronic mail server thatmay transmit a textual message. Communication link 70 may be, forexample, a portion of a communication network such as, for example, aLocal Area Network (LAN), a Metropolitan Area Network (MAN), or a WideArea Network (WAN). The message server 66 may also be in communicationwith the PSTN 12 via communication link 36.

The web server 68 is in communication with the message server 66 viacommunication link 72, and may supply the message server 66 withinformation associated with a subscriber to an emergency notificationservice. Communication link 72 may be, for example, a portion of thecommunication network that includes communication link 70. The webserver 68 may be connected to the Internet 46, and the subscriberinformation may be remotely provisioned and maintained at the web server68 via the Internet 46. Such subscriber information may include, forexample, the subscriber's name, a telephone number associated with thesubscriber, designated telephone numbers, and designated electronic mailaddresses. Designated telephone numbers may be provisioned to receive anotification in the form of an oral message, and designated electronicmail addresses may be provisioned to receive a notification in the formof a textual message, if an emergency communication is placed fromterminal equipment associated with the subscriber. More than fivetelephone numbers and more than five electronic mail addresses may beprovisioned at the web server 68. Provisioning subscriber informationdirectly to the web server 68 reduces the cost and complexity of theemergency notification system.

FIGS. 4A and 4B illustrate an embodiment of a process flow of theemergency notification system 60 of FIG. 3. After the subscriberinformation has been provisioned at the web server 68 via the Internet46, the emergency notification service becomes operational for thesubscriber. The process begins at block 80, where an emergencycommunication is originated from customer premises equipment. Thecustomer premises equipment may be, for example, a landline telephone 26connected to a subscriber line 24.

From block 80, the process proceeds to block 82, where the switch 62receives the emergency communication via the PSTN 12. From block 82, theprocess proceeds to block 84, where the received emergency communicationactivates a trigger defined at the switch 14. The trigger may be anoriginating trigger such as, for example, an N11 trigger, and the N11trigger may be, for example, a 911 trigger. From block 84, the processproceeds to block 86, where the activated trigger causes the switch 62to generate a query message to determine how the emergency communicationshould be processed. The query message may include identificationinformation such as, for example, the telephone number that theemergency communication originated from, the name of the personassociated with the telephone number, and the date and time theemergency communication was received at the switch 62, etc. From block86, the process proceeds to block 88, where the switch 62 transmits thequery message to the STP 20 via communication link 28. From block 88,the process proceeds to block 90, where the STP 20 receives the querymessage and transmits the query message to the database server 64 viacommunication link 30. From block 90, the process proceeds to block 92,where the database server 64 receives the query message originated atthe switch 62.

From block 92, the process proceeds to block 94, where the databaseserver 64 generates a response message to the query message andtransmits the response message to the STP 20 via communication link 30.The response message includes an instruction detailing how the switch 62should process the emergency communication. For example, the responsemessage may include an instruction for the switch 62 to process theemergency communication as a switch-based feature. From block 94, theprocess proceeds to block 96, where the STP 20 receives the responsemessage from the database server 64 and transmits the response messageto the switch 62 via communication link 28. From block 96, the processproceeds to block 98, where the switch 62 receives and interprets theresponse message originated at the database server 64. From block 98,the process proceeds to block 100, where the switch 62 routes theemergency communication to a Public Safety Answering Point (PSAP), wherea PSAP operator processes the call in accordance with well-knownprocedures.

While the process is proceeding from block 92 to block 94, the processalso proceeds from block 92 to block 102, where the database server 64requests a TCP/IP connection be established between the database server64 and the message server 66. Once the TCP/IP connection has beenestablished, the process proceeds from block 102 to block 104, where thedatabase server 64 transmits the identification information included inthe query message to the message server 66 via communication link 70.From block 104, the process proceeds to block 106, where the messageserver 66 receives the identification information, and requests that aTCP/IP connection be established between the message server 66 and theweb server 68. Once the TCP/IP connection has been established, theprocess proceeds from block 106 to block 108, where the message server66 transmits a query message to the web server 68 via communication link72 to determine whether the person associated with the telephone numberthat the emergency communication originated from has been provisioned asa subscriber to the emergency notification service. From block 108, theprocess proceeds to block 110, where the web server 68 receives thequery message and at step 111 determines whether the person has beenprovisioned as a subscriber to the service. If the person has not beenprovisioned as a subscriber to the emergency notification service, theprocess ends at step 113.

If the person has been provisioned as a subscriber to the emergencynotification service, the process proceeds from block 111 to block 112,where the web server 68 transmits the provisioned telephone numbers andelectronic mail addresses to the message server 66 via communicationlink 72. From block 112, the process proceeds to block 114, where themessage server 66 receives the provisioned telephone numbers andelectronic mail addresses, and starts the notification process byplacing outgoing calls to the provisioned telephone numbers via the PSTN12, and/or transmitting textual messages to the provisioned electronicmail addresses over the Internet 46 via the web server 68. Depending onhow the subscriber has provisioned the service, the outgoing calls maybe placed simultaneously or in a sequential order specified by thesubscriber, and the electronic mail messages may be transmittedsimultaneously or in a sequential order specified by the subscriber.According to one embodiment, the outgoing calls are placed concurrentlywith the transmission of the electronic mail messages.

For outgoing calls that are answered by a live person, an answeringmachine, or a voice mail system, the message server 66 may play anannouncement that the call is from an emergency notification service,that the service has received an emergency communication originated froma telephone number associated with the subscriber, the name of thesubscriber, and the date and time the emergency communication wasreceived. Once an outgoing call has been answered at a provisionedtelephone number, and the message server 66 has played the announcement,the message server 66 will stop calling that particular telephonenumber. If an outgoing call has not been answered at a provisionedtelephone number, the message server 66 may continue to call theprovisioned telephone number until the call has been answered and theannouncement has been played.

Electronic mail messages transmitted by the message server 66 to theprovisioned electronic mail addresses may include a textual messagenotifying the person associated with the electronic mail address thatthe message is from an emergency notification service, that the servicehas received an emergency communication originated from a telephonenumber associated with the subscriber, the name of the subscriber, andthe date and time the emergency communication was received. The messageserver 66 may transmit the electronic mail messages once to eachprovisioned electronic mail address. However, if the message server 66receives an indication that the electronic mail message was notdelivered successfully to a particular provisioned electronic mailaddress, the message server 66 may attempt to transmit the electronicmail message to the particular provisioned electronic mail address morethan once.

Although the present invention has been described and illustrated indetail herein with respect to certain embodiments, it is clearlyunderstood that the same is by way of example and is not to be taken byway of limitation. It will be appreciated by those of ordinary skill inthe art that numerous modifications and variations of the presentinvention may be implemented without departing from the spirit and scopeof the present invention as described in the appended claims.
